Answer:

125.5

Step-by-step explanation:

I made the shape in to 2 seperate shapes

the rectangle:8 times 10 is 80

Trapezoid: A=a+b/2(h)

3+10/2(7) is 45.5

so 80+45.5= 125.5

Answer:

[tex] 9 \frac{1}{3} [/tex]

Step-by-step explanation:

Let when x divided by 7 will produce [tex] 1\frac{1}{3} [/tex]

[tex]x \div 7 = 1 \frac{1}{3} \\ \\ x \times \frac{1}{7} = \frac{4}{3} \\ \\ x = \frac{7 \times 4}{3} \\ \\ x = \frac{28}{3} \\ \\ x = 9 \frac{1}{3} [/tex]

Answer:

28 learners

Step-by-step explanation:

Boys : Girls

3 : 4

Since there are 12 boys and 3 units of them...

3 units = 12

1 unit = 12 ÷ 3 = 4

Girls =

4 units = 4 x 4 = 16

Total number of girls and boys: 12 + 16 = 28

Variables are: w & b

Number of terms: 2

Constant: none

Problem 2:

Coefficients are : 6 & -2

Variables are: xy & c

Number of terms: 3

Constant: 4

Problem 3:

Coefficients are : [tex]\frac{2}{3}[/tex] & -3

Variables are: y & p

Number of terms: 2

Constant: none

Step-by-step explanation:

Okay, lets break this down.

An Algebraic expression is not meant to be solved, but rather used to determine the various components inside of it to better understand how to solve equations later on. Although for now lets look at these problems. :

A Coefficient in terms of algebra, is the number before a variable. In other terms, a coeffiecient is the number before the letter such as 3w. Looking at 3w we see that there are two parts: 3, and w.

The number 3 is the coefficient while the variable is the letter w. Variables are always the letters.

Variable: A letter used to determine an unknown value such as x

Now a term is a single mathematical expression. It may be a single number (positive or negative), or a single variable ( a letter). (Can also be a coeffient with a variable multiplied or divided by one another as such :

[tex]3w = 3*w\\\frac{3}{w} = 3 / w[/tex]

 Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

Now with that said, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants.

With all of that said, lets look at the problems given:

Problem 1:

Coefficients are : 3 & 2

Variables are: w & b

Number of terms: 2

Constant: none

Problem 2:

Coefficients are : 6 & -2

Variables are: xy & c

Number of terms: 3

Constant: 4

Problem 3:

Coefficients are : [tex]\frac{2}{3}[/tex] & -3

Variables are: y & p

Number of terms: 2

Constant: none

Made the graph for you since you did not attach any pictures!

The graph of function f(x) = log2 x – 1 is shown in figure.

A relation between a set of inputs having one output each is called a function.

Given that;

The function is,

⇒ f (x) = log 2x - 1

Now,

Since, The function is,

⇒ f (x) = log 2x - 1

Hence, We get;

Answer:

If the arrow is spun 400 times how many times would it be expected to ... 3 green. 20 total 10. Adrian spins the arrow on this spinner once. Which number is the arrow... Part B. Use a paperclip and the tip of your pencil to spin

Answer:

I know this was two weeks ago, but here is my answer: 1/9

Step-by-step explanation:

Baron here is going to spin this twice, and he wants to get a 3 on both, no?

Well, there are 3 sides; 1, 2 and 3, meaning that it will look something like this: ??/3.

He only wants to have one of the options, so that ??/3 will turn into a 1/3.

That would be for one spin, but he's going to do two.

SO, it would be a 1/3 chance of getting it on the first try, and a 1/3 chance on getting it on the second, multiply them together for the complete probability, and BAM you get 1/9.

There is an easier way, but it would take too long to write.

Hope you this helps you understand if you are still confused.

Given:

The figure of a trapezoid.

Length of mid-segment = 5.5

Height of the trapezoid = [tex]6\sqrt{3}[/tex]

To find:

The area of the trapezoid.

Solution:

The area of a trapezoid is:

[tex]A=M\times h[/tex]       ...(i)

[tex]A=\dfrac{a+b}{2}\times h[/tex]

Where, a,b are bases and h is the vertical height.

We know that [tex]M=\dfrac{a+b}{2}[/tex] is the length of the mid-segment.

Putting M=5.5 and [tex]h=6\sqrt{3}[/tex] in (i), we get

[tex]A=5.5\times 6\sqrt{3}[/tex]

[tex]A=33\sqrt{3}[/tex]

Therefore, the area of the trapezoid is [tex]33\sqrt{3}[/tex] units squared.

Answer:

Rate = 10%

Step-by-step explanation:

Given:

Amount deposit = 25,000

Amount get = 26,250

Time = 6 month = 6 / 12 = 0.5 year

Find:

Rate

Computation:

Interest = Amount get - Amount deposit

Interest = 26,250 - 25,000

Interest = 1,250

Interest = P x R% x T

1,250 = 25,000 x R% x 0.5

Rate = 10%

Step-by-step explanation:

If 2 out of 8 of the kittens are white, than 6 aren't white. That fraction would be 6/8 but when you simplify you get 3/4.

The answer is 3/4 of the kittens are not white.

This a simplifed version of 6/8 which is the complement of 2/8, the amount of white kittens.

Answer:

50.3 mm

Step-by-step explanation:

The perimeter of the shaded region = perimeter of a full circle + 2(Length)

= πd + 2(L)
